Investment Objective/Strategy -The First Trust Latin America AlphaDEX® Fund is an exchange-traded fund. The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before the Fund's fees and expenses, of an equity index called the NASDAQ AlphaDEX® Latin America Index.

There can be no assurance that the Fund's investment objectives will be achieved.

The NASDAQ AlphaDEX® Latin America Index is an "enhanced" index created and administered by Nasdaq, Inc. ("Nasdaq")
which employs the AlphaDEX® stock selection methodology to select stocks from the NASDAQ Latin America Index that meet certain criteria.

To construct the Index, Nasdaq ranks the eligible stocks on growth factors including 3-, 6- and 12- month price appreciation, sales to price and
one year sales growth, and separately on value factors including book value to price, cash flow to price and return on assets. All stocks are
ranked on the sum of ranks for the growth factors and, separately, all stocks are ranked on the sum of ranks for the value factors. A stock must
have data for all growth and/or value factors to receive a rank for that style.

Each stock receives the best style rank from the previous step as its selection score.

The top 50 stocks based on the selection score determined in the previous step comprise the "selected stocks". The selected stocks are divided
into quintiles based on their rankings and the top ranked quintiles receive a higher weight within the index. The stocks are equally weighted within each quintile.

Each stock is then tested in order of its selection score rank to check if the weight assigned to that stock is outside the country/sector weighting
constraints, which are set at 15% above the benchmark weight.

If the weight assigned to the stock, when added with the weight assigned to all higher ranking stocks in its country/sector, is greater
than the constraint, then the stock's weight is lowered to the highest rank in the next quintile. Stocks previously lower in rank then move
up one rank. Such stocks in the lowest quintile that violate a constraint are removed from the portfolio and replaced by the highest scoring
stock not originally selected, subject to country/sector constraints. This process continues until all the country/sector weightings meet the constraint.

The price used to calculate market return is determined by using the midpoint between the highest bid and the lowest offer on the stock exchange, on which shares of the Fund are listed for trading, as of the time that the Fund's NAV is calculated.

on a risk-adjusted basis relative to its benchmark.Beta is a measure of price variability relative to the market. Sharpe Ratio is a measure
of excess reward per unit of volatility. Correlation is a measure of the similarity of performance.

*Performance data quoted represents past performance. Past performance is not a guarantee of future
results and current performance may be higher or lower than performance quoted. Investment returns
and principal value will fluctuate and shares when sold or redeemed, may be worth more or less than
their original cost.

After Tax Held returns represent return after taxes on distributions. Assumes shares have not been sold.
After Tax Sold returns represent the return after taxes on distributions and the sale of fund shares. Returns
do not represent the returns you would receive if you traded shares at other times. Market Price returns are
based on the midpoint of the bid/ask spread on the stock exchange on which shares of the fund are listed for
trading as of the time that the fund’s NAV is calculated. Returns are average annualized total returns, except
those for periods of less than one year, which are cumulative.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and
do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax
situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold
their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

**Performance information for the NASDAQ AlphaDEX® Latin America Index is for illustrative purposes only and does not represent actual fund performance.

Indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the performance shown. Indexes are unmanaged and an investor cannot invest directly in an index.

On October 13, 2015, the fund's underlying index changed from the Defined Latin America Index to the NASDAQ AlphaDEX® Latin America Index. Therefore, the fund's performance and historical returns shown for the periods prior to this date are not necessarily indicative of the performance that the fund, based on its current index, would have generated.

The expense ratio for this fund is 0.80%.

MSCI EM Latin America Index - The Index is a free float-adjusted market capitalization-weighted index that is designed to measure the equity market performance of emerging markets in Latin America.

NASDAQ Latin America Index - The Index is a float adjusted market capitalization-weighted index that is designed to measure equity market performance of securities in countries located in Latin America.

Fund shares are purchased and sold on an exchange at their share price rather than net asset value (NAV), which may cause the shares to trade at a price greater than NAV (premium) or less than NAV (discount).

The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.

ETF Characteristics

The fund lists and principally trades its shares on The Nasdaq Stock Market LLC.

The fund's return may not match the return of the NASDAQ AlphaDEX® Latin America Index. Securities held by the fund will generally not be bought or sold in response to market fluctuations.

Investors buying or selling fund shares on the secondary market may incur customary brokerage commissions.
Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net
asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be
redeemed directly from the fund by authorized participants, in very large creation/redemption units. If the fund's authorized participants are unable
to proceed with creation/redemption orders and no other authorized participant is able to step forward to create or redeem, fund shares may trade at
a discount to the fund's net asset value and possibly face delisting.

Risk Considerations

The fund's shares will change in value, and you could lose money by investing in the fund. One of the principal risks of investing in the fund is market risk. Market risk is the risk that a particular stock owned by the fund, fund shares or stocks in general may fall in value. There can be no assurance that the fund's investment objective will be achieved.

The fund may invest in securities issued by companies concentrated in a particular sector or country which involves additional risks including limited diversification. The fund may invest in small capitalization and mid capitalization companies. Such companies may experience greater price volatility than larger, more established companies.

An investment in a fund containing securities of non-U.S. issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers. These risks may be heightened for securities of companies located in, or with significant operations in, emerging market countries.

The value of fund shares may be adversely affected by political, economic, and social instability, inadequate investor protection, changes in laws or regulations of countries within Latin America, international relations with other nations, natural disasters, corruption and military activity. The economies of many Latin American countries differ from the economies of more developed countries in many respects. Certain Latin American countries are highly dependent upon and may be affected by developments in the U.S., Europe and other Latin American economies.

The fund may invest in depositary receipts which may be less liquid than the underlying shares in their primary trading market. The fund may, under most circumstances, effect a portion of creations and redemptions for cash, rather than in-kind securities. As a result, the fund may be less tax-efficient.

Changes in currency exchange rates and the relative value of non-US currencies may affect the value of a fund's investments and the value of a fund's shares.

The fund is classified as "non-diversified" and may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers.
